Rubber-toughened nanocomposites (RTNC) consisting of a series of compatibilized polyamide 6 / polypropylene (PA6/PP) blends, polyethylene-octene elastomer (POE) and organophilic modified montmorillonite (organoclay) were produced by melt compounding followed by injection moulding. Polypropylene grafted maleic anhyride (PPgMA) was used as compatibilizer. The incorporation of organoclay significantly increased the stiffness and strength but at the expense of the toughness. Conversely, the incorporation of the POE increased the toughness, while the strength and stiffness decreased. The modulus...
